I DID paint a peony recently, so I thought you'd like to see some step pics and hear about the process.
So, I shot a photo of this peony in my garden, a nice, clear close-up. After sketching it out large, I started with an entire wet on wet wash over the whole page with Indian Yellow and Permanent Rose. I tried to stay out of the areas that were white where the sun was the strongest. This wash should be loose and quick.
Here it is framed!
Happy painting, my fellow artists!
